That's because we measure mileage using miles/gallon, and *diesel has more energy per gallon than gasoline*. About 30% more, in fact. That's like saying that a P-M is better than an Athlon 64 because it gets more work done "per clock". That's not the unit you need to be evaluating.
"Unfortunately the stigma in the US over "diesel" prevents them from being brought over here."
It's not the stigma, it's the envrionment. Even "clean" diesel engines rank horribly on particulate, NOx, and other nasty emissions.
The Prius *wasn't* designed to get the best gas mileage period. It was designed to reduce emissions *and* get good fuel economy. The Prius actually burns gas when it doesn't have to so that the catalytic converter stays hot (it doesn't work otherwise).
"Hybrids are a bad idea, twice the weight (batteries, two motors), half the interior room."
That's bullshit. The entire THSD - including the batteries and motor - is around 800lbs. This is *easily* offset by the fact that the Prius doesn't need a wasteful transmission. You might be able to save 400lbs using a vehicle with a manual transmission, but that's not really comparable to the automatic Prius, is it?
Oh, and your precious diesel cars? They weigh more than their gasoline counterparts because diesel engines need stronger components (much higher compression).
And, half the interior room? What kind of crap is that? The batteries in the Prius don't take up much room at all - and the engine compartment isn't any bigger than the one on any other medium-small car.
"Diesel-engined cars have been getting 50+ MPG for years and years."
The Prius hits 50mpg in real-world testing, too, with fuel that has 30% less energy than diesel.

It's also capable of running on gas, like a hybrid, so you can use it normally while you wait for the filling stations to propogate.
The air compression uses electricity. Whether that electricity was generated *cleanly* or not is irrelevant to the car itself.
The whole point is that 80% of vehicle emissions are released in densely populated city centers, and the quality of air in big cities is declining. When the local news is issuing "smog warnings" during the summer, somethings wrong.
